Using std::pair with Custom Types

Yes, you can use std::pair with your own custom types. std::pair is a template that accepts any two types as its template arguments. Here's an example:

1#include <iostream>
2#include <utility>
3
4class Player {
5 public:
6  std::string name;
7  int level;
8};
9
10class Guild {
11 public:
12  std::string name;
13};
14
15int main() {
16  std::pair<Player, Guild> PlayerGuild;  
17
18  PlayerGuild.first.name = "Anna";
19  PlayerGuild.first.level = 42;
20  PlayerGuild.second.name = "Adventurers";
21
22  std::cout
23    << "Player: " << PlayerGuild.first.name
24    << " (Level " << PlayerGuild.first.level
25    << ")\nGuild: " << PlayerGuild.second.name;
26}

1Player: Anna (Level 42)
2Guild: Adventurers

In this example, we define two custom types: Player and Guild. We then create a std::pair named PlayerGuild that stores a Player as its first element and a Guild as its second element.

We can access and modify the members of our custom types using the first and second member variables of the pair, as shown in the example.

Remember to include the <utility> header to use std::pair in your code.
